Q: Is it possible to replace the Bluetooth card to 4.0 to use Handoff

The Bluetooth chip is soldered to the logic board in the iMac so finding someone with the skills is going to be very expensive.

i m not able to use airdrop and contacted apple genius bar according to the genius he has the same imac and he is able to use airdrop however he examined mine and it would not work so i ask if he could take the imac in for further investigation and if need be upgrade the bluetooth card which would cost something around 100 dollars

I'm not sure it is soldered. The iFixit guide shows how to replace the bluetooth board for this iMac: https://www.ifixit.com/Guide/iMac+Intel+27-Inch+EMC+2429+Bluetooth+Board+Replace ment/7553

The question would be if a newer bluetooth board will fit and be recognized by the OS to allow handoff, and I would also be interested in this.

There are no Apple support people here - these are user to user forums for the most part.

@ Thomas Smith3:

I can't find anything about having to have BT 4 - can you post a link to that info?

Here's what I found: requirements for Handoff:

OS X Yosemite: null

from here:

OS X Yosemite: Pick up where you left off with Handoff

this is where the bluetooth card is located on the iMac 27 mid2011 - this should be a very easy replacement, provided someone can identify the proper Bluetooth 4.0 compatible component to use as a replace part.

The OP has a 2012, not 2011. - Oops, never mind, his is a 2011 model purchased in 2012.
